Default Heating and Ventilation vacuum diagram

Good morning, hope someone can point me in the direction of a line diagram for my XJ6C heater vacuum piping. The tubing connectors have perished and dropped off. I have replaced a most and tested the main flaps etc with a small vacuum pump but when operating I am still losing vac somewhere.
A diagram will help, I'm sure, or, I just muddle along testing until I find the problem. Just so awkward to get to everything!
Thank you

Thanks from here as well. As clear a diagram that I've ever seen. I saved it for adding to my Jag lore.

It's been on the cold side around here. 50's F. I was going to use my Jeep for errands as I fancied it's strong warm air production.

But, the Jaguar beckoned. It must've been challenged!! It fired right up and purred/ After just a bit I set the temp on 85 and the fans to Defrost. I was greeted with a pleasant flow of warmth. Actually 1/2 way to the first stop, I backed the temp way down. The cat asserted itself.
